In this study, we developed an acceleration technique combining compressed sensing (CS), parallel imaging (PI) and partial Fourier (PF) for the fresh blood imaging (FBI) sequence. Then, we evaluated the influence of the pattern design parameters and explored the optimal values for these parameters. By using the optimised sampling patterns, the FBI acquisition can be accelerated up to 10 times while the image quality is maintained.
